This course offers an introduction into the public economics theory. It does not aspire to cover theories of taxation, public expenditures, regulation etc. at length and in-depth. Rather, our ambition is to give a bird's-eye view of central themes of public economics and related disciplines, and teach concepts, logic, and ideas, rather than methods of analysis, which would require an entirely different course format.
Our choice of topics covered by the course reflects a trade-off between salience and centrality, on the one hand, and suitability for a brief online introductory course, on the other. The course content is neither comprehensive (which would be a "mission impossible" for virtually any public economics course"), nor representative of other such courses. With these limitations and caveats in mind, we encourage our students to continue their public economics studies in a more regular fashion, and see our role inter alia in motivating interest in such "continued education".
The central theme of the course is the role of government as a mechanism of resource allocation which complements and augments markets. Governments are viewed as public agencies set to correct market failures. Such agencies however are prone to failures of their own, and hence markets and governments are two imperfect alternatives. We deal with government's limitations, with particular emphasis on those that have to do with informational asymmetry, limited administrative capacity, and imperfect accountability to society. Otherwise the course's man themes are economics of taxation, regulation, politics of public economics, incentives in government, and government vis-à-vis (civil) society.

Design of Government: A Tax Theory Primer

This lecture covers the positive and normative theories of taxation, ways and means to collect public revenues, and existing informational, administrative, political constraints governments have to deal with. We consider lump sum tax as first best option which implementation in practice, unfortunately, is severely restricted by informational asymmetry. Then follows a cursory introduction into one of the most beautiful (but also most technically complex) parts of public economics which characterizes optimal tax schedules minimizing welfare losses subject to information constraints; such analysis is carried out in the so-called Mirrlees economy. Another focal point of the lecture is the role of elasticity in selecting taxes and how the concept of elasticity can be applied to the analysis of time inconsistency in taxation.
